37.5 by Cocona
37.5 by Cocona Technology has active particles that work with your body to keep you dry by actively moving moisture and accelerating evaporation. Comfort in clothing is greatly influenced by the temperature and humidity next to skin known as the microclimate. For the average person, the body strives to maintain an ideal core body temperature of 37.5° C. You are most comfortable when the microclimate next to your skin has a relative humidity close to 37.5%. When you are in this ideal 37.5 comfort zone, you are also in your ideal performance zone. 37.5 technology helps your body manage the moisture in your microclimate to keep you in this '37.5 zone' of comfort and performance.
Merino Wool is the best choice for socks, hats, base layers and mid layers because of its wicking qualities, enormous temperature spectrum and natural resistance to odor.
Camouflage on each separate layer of your kit allows for proper concealment no matter what weather conditions.
I had this shirt already in ASAT and wanted to pick up one in Fusion. The First Lite website was out of stock, but low and behold BobWards had one. Great baselayer. I wear it under my Chama or Halstead Tech fleece when snow skiing, snowshoeing, hiking or hunting. Very lightweight but does the trick. Highly recommend.
